ligaments.

A. THE ANTERIOR LIMB MUSCLES. 
Superficial muscles of the shoulder and chest region 
(Identify the dorsolumbar fascia which covers all but the most superficial muscles of the 
back, and is continuous anteriorly with the cervical fascia.) 
Name of muscle 
Origin 
Insertion 
1. Trapezius. 
From the dorsolumbar fas¬ 
cia, and along the mid¬ 
dorsal line over the spinous 
processes of the thoracic 
and cervical vertebrae, and 
from the occipital protuber¬ 
ance of the skull. 
Metacromion process, supra¬ 
scapular fascia, and dorsal 
half of spine of scapula. 
2. Latissimus dorsi. 
Partly from the dorsolumbar 
fascia, partly from the three 
posterior ribs. 
Medial surface of shaft of 
humerus. 
3. Levator scapulae. 
Base of the skull. 
Metacromion process. 
4. Sternomastoideus. 
Anterior end of sternum. 
Mastoid process of skull. 
5. Cleidomastoideus 
Clavicle. 
Mastoid process of skull. 
6. Occipitohumeralis. 
Base of the skull. 
Lateral third of clavicle. 
7. Cleidodeltoideus. 
Lateral half of clavicle. 
Deltoid tuberosity of hum¬ 
erus. 
8. Acromiodeltoideus. 
Acromion process of scapula. 
Deltoid tuberosity of hum¬ 
erus. 
9- Spinodeltoideus. (More con¬ 
veniently studied in con¬ 
nection with the muscles 
of the scapula.) 
Infraspinous fascia, the spine 
of the scapula, acromion 
and metacromion. 
Lateral surface of humerus 
distal to its head. 
10. Pectoralis major, consisting 
of many divisions. 
Sternum. 
Deltoid tuberosity (ridge) 
of humerus. 
Deeper muscles of the shoulder and chest region 
11. Pectoralis minor. 
Sternum. 
Clavicle and supraspinous 
fascia. 
12. Rhomboideus major. 
Spines of anterior thoracic 
vertebrae. 
Vertebral border of scapula. 
13. Rhomboideus minor. 
Spines of cervical vertebrae. 
Vertebral border of scapula. 
14. Rhomboideus capitis. 
Lateral surface of the skull 
posterior to the ear. 
Vertebral border of scapula. 
15. Serratus anterior. 
By digitations from the 
lateral region of the third 
to ninth ribs. 
Vertebral border of scapula. 
16. Levator anguli scapulae. 
Transverse processes of pos¬ 
terior five cervical ver¬ 
tebrae. 
Costal surface of scapula 
close to its vertebral border. 
Muscles on the costal surface of the scapula 
17. Teres major. 
Axillary border of scapula 
Shaft of humerus near 
insertion of the latissimus 
dorsi.
